I'd love to see m3u-synchronisation being added to Strawberry. This would make playlist synchronisation across multiple devices possible.
This would include live or periodical actualisations when the m3u-file is changed by another party and updated m3u-files for every playlist-change taken in Strawberry
A change like this has already been implemented to android foss-software like PixelplayerOSS (alpha) so if Strawberry supported the feature, the apps could be sync'd and used together flawlessly.
